This is a question that I sometimes think about. In general, mental health can be considered a taboo subject, especially in certain cultures. In the culture my family is from (Carribean), there is next to no support if you struggle with mental health issues - you are either expected to hide them or get over it.
Although the topic of mental health is well known in the UK, I feel that support can be improved - I feel at times, therapists don't really understand autistic individuals as they may not be specialised in the subject (if I make sense). It is like some of them offer advice that is more designed for neurotypicals - either that or in most cases you are often expected to spend money on medication that doesn't help alleviate issues. For example with depression, I used to be prescribed antidepressants then stopped taking them cold turkey because I felt I was wasting money on something that doesn't work well. If you take medication, I don't judge as everyone is different - for my overall perspective I prefer to manage depression by journaling or doing creative writing as it allows me to get thoughts out.
I also think in the case of working, there seems to be a lot of widespread awareness on mental health but when you talk to employers about it, they either become judgemental or they will try to force you out of the workplace because in their eyes, you are a liability(?) that will cost the company.
I am not sure if others feel this way but was curious to hear general opinions.
